In meiosis, there are two rounds of the M phase, resulting in four haploid cells that aren't … Web16 okt. 2024 · Prophase is the first stage of mitosis, so when the cell enters this stage, it will have twice as much genetic material (which doubles during the S phase of the cell cycle). Also, an achromatic spindle is formed, the nuclear membrane disappears and the chromosomes condense.
